| 摘 要： | 考虑水泥土与型钢的相互作用，对SMW工法组合梁进行分项刚度计算，得到了弹性阶段SMW工法组合梁的刚度。基于弹性力学能量原理，导出了SMW工法型钢水泥土简支组合梁双集中力下的荷载-跨中挠度方程。利用分项刚度计算与荷载-挠度方程对两种截面形式的SMW工法组合梁进行抗弯性能分析，结果表明在弹性阶段与数值结果吻合较好。

| Abstract: | Flexural rigidity of SMW engineering method combination beam is calculated by subentry based on considering interaction of cement soil and shaped steel. Flexural rigidity of SMW engineering method combination beam of elastic stage is obtained. Load-midspan flexivity of SMW engineering method combination beam is deduced under double concentrated force based on energy principle of elastic mechanics. Bending resistance performances of two section forms of SMW engineering method combination beam are analyzed based on above research work. And it is shown that the analysis is consistent with numerical result well. |
